Comments

12.2B at the start of the boil (grain only). Sugars added at 30 minutes, slowly and with low flame. Very fast start to the ferment which was carried out at 66F. On 2017-12-19 after the krausen had mostly fallen, the carboy was placed on a heating pad set to '4' and the temperature increased to 74F to encourage attenuation.
